I'm Dmytro Andriushchenko, a full-stack and AI developer based in Richmond Hill, Ontario — serving the Greater Toronto Area and working remotely with clients worldwide. Since 2019 I have designed, built, and shipped 150+ websites and web applications for businesses of every size, from local companies to large industrial suppliers. You can browse a selection of delivered projects on this site.
Business and marketing websites, e-commerce stores, dashboards, client portals, and SaaS products — built with React, Next.js, TypeScript, and Node.js on MongoDB or PostgreSQL. Fast, accessible, search-engine-friendly, and maintained long after launch. See the web development services and e-commerce development pages, or more about my background on the about page.
I put AI to work inside real products: chat assistants grounded in your own data with retrieval-augmented generation (RAG), AI agents that complete multi-step tasks with your approval, MCP servers that connect assistants to business systems, and voice interfaces — using the Anthropic Claude and OpenAI APIs. See the AI integration services page, or the FAQ that explains agents, RAG, and MCP in plain language.
When off-the-shelf software does not fit, I build custom ERP and CRM systems — invoicing, inventory, client management, dashboards — and integrate websites with payments (Stripe), email, and CRM/ERP platforms like HubSpot, Salesforce, and QuickBooks. Ready to talk about your project? Get in touch.
